Fractionating and further cracking a C6 fraction from a naphtha feed for propylene generation |
| 摘要 |
The present invention relates to a process for selectively producing C<SUB>3 </SUB>olefins from a catalytically cracked or thermally cracked naphtha stream by fractionating the naphtha feed to obtain a C<SUB>6 </SUB>fraction and feeding the C<SUB>6 </SUB>fraction either in the riser downstream of the injection point for the reminder of the naphtha feed, in the stripper, and/or in the dilute phase immediately downstream or above the stripper of a process unit.
